Nsi Industries RD16NA-BK 1/2 Inch Npt Nm Dome Cord

Product Description

The NSI INDUSTRIES RD16NA-BK is a 1/2 inch NPT dome-style cord connector designed for use with nonmetallic (NM) cable entries. It provides a secure, strain-relieved termination point where NM cable enters an electrical enclosure, junction box, or panel. The dome connector threads directly into a 1/2 inch NPT knockout opening, creating a neat and code-compliant cable entry. Electricians and electrical contractors use this fitting during rough-in and finish wiring work on residential and light commercial installations. The black finish suits standard enclosure aesthetics.

This connector is suited for residential and light commercial wiring applications where NM cable must be secured at the point of entry into an electrical box or enclosure. It is commonly installed in panel boxes, junction boxes, and subpanels. The 1/2 inch NPT thread size is among the most common knockout sizes in residential electrical work, making this fitting a frequently stocked item for service technicians and electrical contractors.

Key Features

• 1/2 inch NPT thread for direct installation into standard knockout openings
• Dome-style design provides strain relief and a clean cable entry point
• Compatible with nonmetallic (NM) sheathed cable

Compatibility

Designed as a standard replacement or new-installation dome cord connector for use with 1/2 inch NPT knockout openings on electrical enclosures, junction boxes, and panels accepting nonmetallic sheathed cable.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize the circuit and verify the panel or enclosure is fully powered down before installing or replacing any cable connector. Thread the connector into the 1/2 inch NPT knockout by hand, then tighten with an appropriate wrench to ensure a secure, strain-relieved fit. Do not overtighten, as this may damage the connector body or the enclosure knockout threads.
